Parasitism Of Greenbugs (Homoptera: Aphididae) By Lysiphlebus Testaceipes (Hymenoptera: Braconidae) In Grain Sorghum: Implications For Augmentative Biological Control, Odair A. Fernandes, Robert J. Wright, Z. B. Mayo

Department of Entomology: Faculty Publications

Field cage studies were conducted to describe the relationship between the percentage of Lysiphlebus testaceipes (Cresson) parasitism (as measured by aphid mummies) and densities of greenbug, Schizaphis graminum Rondani, on grain sorghum, Sorghum bicolor L. In 1993 and 1994, a biotype E-susceptible grain sorghum hybrid was grown in field cages and L. testaceipes adults were released after each plant was infested with 20 biotype E greenbugs. The release rates were 0, 0.5, 1.0, and 2.0 wasps per plant in 1993, and 0, 0.16, 0.33, and 0.5 wasps per plant in 1994. Greenbugs and mummies were counted 1-2 times a week …

Effects Of Food Deprivation, Age, Time Of Day, And Gamma Irradiation On Attraction Of Mexican Fruit Flies (Diptera: Tephritidae) To Two Synthetic Lures In A Wind Tunnel, David C. Robacker

Entomology Papers from Other Sources

The physiological condition of Mexican fruit flies, Anastrepha ludens (Loew), affected their attraction to 2 similar but qualitatively different synthetic lures in wind-tunnel bioassays. The 2 lures were BioLure (ammonium acetate and putrescine) and AMPu (ammonium carbonate, methylamine HCI, and putrescine) . Effects of food deprivation on attraction to the lures were smaller than the effects of sex, time of day, and irradiation. Sugar-fed, protein-starved flies were attracted more strongly than other hunger-status groups to the lures. Sugar-starved, protein-starved females were less responsive than other groups of females to AMPu. Protein-starved males were more responsive than protein-fed males to BioLure. …

Two New Nymphalidae From Western North Carolina: New Subspecies Of Speyeria Aphrodite And Phyciodes Batesii, Ronald R. Gatrelle

The Taxonomic Report of the International Lepidoptera Survey

Two new subspecies are described from Macon County, North Carolina, United States. Speyeria aphrodite cullasaja is characterized by dorsal melanism, especially in females, by usually lacking the dorsal FW basal spots in cell Cu1 and Cu2, and by a narrowed buff marginal band on the ventral HW (sometimes absent in females). Phyciodes batesii maconensis males are characterized by wholly yellow ventral hind wings devoid of any dark marginal dusting or whitish crescents; and females occasionally possessing, lightly dusted, brown margins and rarely having a silvered marginal ventral HW spot. PPhyciodes batesii maconensis larvae are gregarious Aster feeders. Females are …

The Rediscovery, Taxonomy, And Biology Of Chlosyne Gorgone Gorgone And Chlosyne Ismeria (Nymphalidae) In Burke County, Georgia, Ronald R. Gatrelle

The Taxonomic Report of the International Lepidoptera Survey

On April 24, 1993 a colony of Chlosyne gorgone gorgone was found in Orangeburg County, South Carolina, United States. This led to the rediscovery on April 27, 1993 of C. g. gorgone at its type locality in Burke County, Georgia. This species had not been seen or collected anywhere in east coastal Georgia or coastal South Carolina since its description in 1810. The type locality is xeric, scrub oak sandhill. This habitat is generally unsuitable for the survival of later broods. The larvae of nominate gorgone have only been found on Helianthus divaricatus. Topotypical gorgone differ slightly, …

Viral And Insect Genes That Inhibit The Immune System And Methods Of Use Thereof, Bruce A. Webb, Liwang Cui

Entomology Faculty Patents

Viral, endoparasitoid and/or host genes that specifically inhibit the immune response of insect pests, useful for broadening the host range of insect viruses. Symbiont viruses of insect pests are genetically modified to express immune-suppressing proteins or biologically active fragments thereof and, optionally toxins, to increase the virus host range and/or improve the efficacy of insect pathogens.

"Insects" From Atlas Of The Sand Hills, Brett C. Ratcliffe

University of Nebraska State Museum: Entomology Papers

Because the Sand Hills are, for the most part, a treeless landscape of grass-covered sand dunes, most of the insects are adapted to sandy habitats and a dry, continental climate, as well as to the kinds of plants and other animals that live there. Unlike most forest-adapted species, insects in the Sand Hills tolerate drier and windier conditions and greater solar radiation. They have also been successful in surviving the periodic fires that are so necessary for maintaining native grasslands. In fact, the mosaic of habitats partially created by fire has probably contributed to increased insect diversity in the Sand …

Beneficial Arthropods Associated With Buffalograss, Tiffany Heng-Moss, Frederick P. Baxendale, Terrance P. Riordan

Department of Entomology: Faculty Publications

Beneficial arthropods collected from buffalograss, Buchloe dactyloides (Nuttall) Engelmann, evaluation plots and vegetatively established buffalograss lawns included predatory ants, spiders, ground beetles, rove beetles, big-eyed.bugs, and several species of hymenopterous parasitoids. Ants and spiders were the most abundant beneficial arthropods collected, representing 84% of the total beneficial arthropods captured. Pitfall traps collected >2.5 times as many (16,094) beneficial arthropods as sod plug samples (6,054), demonstrating that pitfall traps are a more effective technique than sod plugs for capturing highly mobile surface-dwelling arthropods. Families of parasitoids captured on sticky traps during the 2-yr sampling period included Scelionidae, Encyrtidae, Mymaridae, and Trichogrammatidae. …

An Addendum To Anthocharis Midea Dos Passos And Klots 1969: Description Of A New Subspecies From Texas, Ronald R. Gatrelle

The Taxonomic Report of the International Lepidoptera Survey

This paper verifies and expands upon the information presented by dos Passos and Klots in their 1969 systematic revision of Anthocharis midea. Their restriction of the range of A. midea midea to the coastal islands and immediate coast of Georgia and South Carolina, United States is confirmed and expanded north into southern coastal North Carolina. Their range of A. m. annickae is expanded southward from Virginia to central Georgia. A new subspecies, A. midea texana, is described from Texas. Texana is annickae’s ancestor. It differs from annickae only in having greatly reduced black scaling …

Diversity And Dominant Species Of Ground Beetle Assemblages (Coleoptera: Carabidae) In Crop Rotation And Chemical Input Systems For The Northern Great Plains, Michael M. Ellsbury, Janine E. Powell, Frank Forcella, W, David Woodson, Sharon A. Clay, Walter E. Riedell

Agronomy, Horticulture and Plant Science Faculty Publications

Dominant carabid species present in crops and crop rotation sequences commonly used in the northern Great Plains were assessed as an initial step toward the management of carabids as natural control agents. Ground beetle populations were determined by pitfall trapping in 4 crop rotation treatments maintained under high, managed, and low levels of chemical fertilizer and pesticide inputs. Diversity and species richness among crops, rotations, and input levels were compared using 3 indices—the Shannon-Weaver Index, relative diversity, and the Hierarchical Richness Index (HRI). Four carabid species, Cyclotrachelus altemans (Casey), Poecilvs lucublandus Say, Harpalns pensylvanicus (DeGeer), and Bembidion quadrimaculatum L., comprising …

A New Tribe, Genus, And Species Of Limnichid Beetle, Woolridgeus Perforatus, From Malaysia (Coleoptera: Limnichidae: Wooldridgeini), Paul J. Spangler

Insecta Mundi

A new tribe is established in the Limnichidae, Limnichinae, for a new genus and species, Wooldridgeus perforatus, from Sabah, Malaysia. Two autapomorphic characters distinguish Wooldridgeini from the two other tribes of the subfamily Limnichinae; 1) the mesotarsus and metatarsus join their respective tibia ventrally (medially) and preapically instead of the usual apical only connection and 2) a large pore, presumed to be an opening of a prothoracic gland, is present on each hypomeron. Distinguishing characters are illustrated by scanning electron micrographs and line drawings. A key to the three tribes included in the Limnichinae is provided.
